X
Accelerate the vehicle to the desired speed. X
Briefly press the cruise control lever up C or
down D .X
Remove your foot from the accelerator pedal.
Cruise control is activated. The vehicle auto-
matically maintains the stored speed.
i Cruise control may be unable to maintain
the stored speed on uphill gradients. The
stored speed is resumed when the gradient
evens out. Cruise control maintains the
stored speed on downhill gradients by auto-
matically applying the brakes.
Storing the current speed or calling up
the last stored speed
G WARNING
If you call up the stored speed and it is lower
than the current speed, the vehicle deceler-
ates. If you do not know the stored speed, the
vehicle could decelerate unexpectedly. There
is a risk of an accident.
Pay attention to the road and traffic condi-
tions before calling up the stored speed. If you
do not know the stored speed, store the
desired speed again. X
Briefly pull the cruise control lever towards
you

To avoid damage to the vehicle, deactivate
these systems in the following or similar sit-
uations: R

Distance Pilot DISTRONIC can neither reduce
the risk of an accident if you fail to adapt your
driving style nor override the laws of physics.
Distance Pilot DISTRONIC cannot take into
account road, weather or traffic conditions. Dis-
tance Pilot DISTRONIC is only an aid. You are
responsible for maintaining a safe distance to
the vehicle in front, for vehicle speed, for brak-
ing in good time and for staying in lane.
Do not use Distance Pilot DISTRONIC: R
in road and traffic conditions which do not
allow you to maintain a constant speed, e.g. in
heavy traffic or on winding roads R
on slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid R
in poor visibility, e.g. due to fog, heavy rain or
snow
Distance Pilot DISTRONIC may not detect nar-
row vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line.
In particular, the detection of obstacles can be
impaired if: R
there is dirt on the sensors or anything else
covering the sensors R
there is snow or heavy rain R
there is interference by other radar sources R
there are strong radar reflections, for exam-
ple in parking garages
If Distance Pilot DISTRONIC no longer detects a
vehicle in front, it may unexpectedly accelerate
to the speed stored.
This speed may: R
be too high if you are driving in a turning lane
or an exit lane R
be so high in the right lane that you pass vehi-
cles driving on the left (in countries where
they drive on the right) R
be so high in the left lane that you pass vehi-
cles driving on the right (in countries where
they drive on the left)
If there is a change of drivers, advise the new
driver of the speed stored. Cruise control lever

Distance Pilo t DISTRONI C wit h Steering
Pilo tGeneral notes
Distanc e Pilo t DISTRONIC wit h Steerin g Pilo t
aids you in keepin g th e vehicle in th e middle of
th e lan e by means of moderat e steerin g inter-
vention s in a speed range from 0 – 12 5 mph
(0 - 20 0 km/h).
It monitors th e are a in fron t of your vehicle by
means of multifunction camera C , fixed at th e
to p of th e windshield .
In a speed range from 0 - 37 mph (0 - 60 km/ h) ,
Steering Pilot focuses on the vehicle in front,
taking into account lane markings, e.g. when
following vehicles in a traffic jam.
At speeds of more than 37 mph (60 km/h),
Steering Pilot focuses on clear lane markings
(left and right), focusing on the vehicle in front
only if clear lane markings are not present.
If these conditions are not present, Steering
Pilot cannot provide assistance.
Distance Pilot DISTRONIC must be active in
order for the function to be available.
Important safety notes
Distance Pilot DISTRONIC and Steering Pilot can
neither reduce the risk of an accident if you fail
to adapt your driving style nor override the laws
of physics. Distance Pilot DISTRONIC with
Steering Pilot cannot take into account road,
weather or traffic conditions. Distance Pilot
DISTRONIC with Steering Pilot is only an aid.
You are responsible for maintaining a safe dis-
tance to the ve hi
cle in front, for vehicle speed,
for braking in good time and for staying in lane.
Distance Pilot DISTRONIC with Steering Pilot
does not detect road and traffic conditions and
does not detect all road users. If you are follow-
ing a vehicle which is driving towards the edge of
the road, your vehicle could come into contact with the curb or other road boundaries. Be par-
ticularly aware of other road users, e.g. cyclists,
that are directly next to your vehicle.
Obstacles such as traffic markers on a con-
struction site that are on the lane or projecting
out into the lane are not detected.
An inappropriate steering intervention, e.g. after
intentionally driving over a lane marking, can be
corrected at any time if you steer slightly in the
opposite direction.
DISTRONIC PLUS with Steering Pilot cannot
continuously keep your vehicle in lane. In some
cases, steering intervention is not sufficient to
bring the vehicle back to the lane. In such cases,
you must steer the vehicle yourself to ensure
that it does not leave the lane.
The system may be impaired or may not function
if: R
there is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray R
there is glare, e.g. from oncoming traffic, the
sun or reflection from other vehicles (e.g. if
the road su rface i s wet) R
the windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera R
there are no or several unclear lane markings
for one lane, e.g. roadworks R
the lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow R
the distance to the vehicle in front is too short
and thus the lane markings cannot be detec-
ted R
the lane markings change quickly, e.g. lanes
branch off, cross one another or merge R
the road is narrow and winding R
there are highly variable shade conditions on
the roadway
The system is switched to passive and no longer
assists you by performing steering interventions
if: R
you actively change lane R
you switch on the turn signal R
you take your hands off the steering wheel or
do not steer for a prolonged period of time
After you have finished changing lanes, Steering
Pilot is automatically active once more.Driving systems 177
Driving and parking Z

Steering Pilot cannot provide assistance: R
on very sharp corners R
when towing a trailer R
when a loss of tire pressure or a defective tire
has been detected and displayed
Pay attention also to the important safety notes
on Distance Pilot DISTRONIC ( Y
page 171).
The steering interventions are carried out with a
limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with
a visual warning. A steering wheel symbol
appears in the multifunction display. If you have
still not started to steer and have not taken hold
of the steering wheel, a warning tone also
sounds to remind you to take control of the
vehicle after five seconds at the latest. Steering
Pilot is then switched to passive. Distance Pilot
DISTRONIC remains active.

HOLD function
General notes The HOLD function can assist the driver in the
following situations: R
when pulling away, especially on steep slopes R
when maneuvering on steep slopes R
when waiting in traffic
The vehicle is kept stationary without the driver
having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.178
